Application filed November To all whom. it may concern? 3e it known that i, FREDERZCA W. -HOLD, citizen of the United States, residing at Mount Vernon, in the county of i festchester and State of New York, have invented certain new and useful improvements in Ventilating-Sash and vi indowdioeking Devices, of which the following is a specification.

This invention relates to means for holding window-sashes in partially open positions as well as to permit of a limited movement of either or both sashes, so that an opening may be had at the top and bottom of the window, if desired, and thus it provides for the ventilation of apartments, while at all times affording absolute security from intrusion.

The device is intended to be applied to the inner surface of the side pieces or stiles of window-sashes so as to be entirely hidden from outside view. The extent of the opening of the sashes being determined by the distance apart the stops and guide-blocks are placed, which, consequently, regulates the length of movement of the rods.

The invention is clearly shown in the accompanying drawing, whereon Figure 1 represents the inside of a window frame, its upper and lower sash and my locking device in connection with same, Fig. 2 is a vertical crosssection of the adjacent portions of the two sashes with my device applied thereto, Fig. 3 is an enlarged view of the locking device, the window sashes and a part of the window frame, and Figs. 4, 5, 6, and 7 are detail views of the locking device all of which are hereinafter fully described.

On the drawing the letter A designates a window frame and B, B the sashes thereof.

A guide block a, having a vertical rodhole a thereon, is firmly fastened to the side piece or stile of the upper sash, with one or more screws (H, the head of the screws rest ing in rear of the vertical rod-hole a so as not to interfere with the movement of a rod d, which in practice, operates in said. hole.

A block I), which is adapted to rest on the top of the meeting-rail of the lower sash, has upper and lower projecting rods d, (6 connected with the respective ends thereof, either by screw threads 6, e or other suitable means, so that the upper rod (i shall operate in the vertical hole of the guide-block a, and the lower rod d in the vertical hole of a lower guide-block c, the latter secured to the lower sash by means of screws in like manner with the upper guide-block a.

g The lower guide-block c is somewhat similar to the top guide-block a except that a slot 0 is cut from one side into the upper half of the guidablock, meeting the vertical hole in which the lower projecting rod (Z is adapted to operate; this feature being added to offer additional security by way of preventing the rod from being shaken or pushed out of place should the locking bar be moved upward by any means from the exterior of the window. lower guide-block c is also provided with 1.116 a set-screw 9 preferably with its head sunk below the surface of the block, so that a soeket-wrench will be required to operate same to lock or release the lower rod of the locking device. This feature being particularly desirable in institutions or apartments where demented or delirious persons are confined.

As a substitute for the set-screw, the guideblock may be provided with any known form of lock requiring a key for operating same.

It will be noted that the invention is not intended to be used to fasten the two sashes together so that they cannot be moved, but rather to permit the limited movement of one or both sashes the construction and application of my device being such as to permit of this being done with perfect safety, as it is obviously impossible to remove the locking device until both sashes 1 are completely closed.

If preferred, the guid e-rods may be hinged to the locking-bar or the said locking-bar may be hinged at or near its center to facilitate the insertion of the rods in the guideblock a, (1,.

Having described my invention, what I claim as new and desire to secure by Letters Patent is:

1. As a new article of manufacture, a sash holder, comprising the combination of a block having ends provided with oppositely projecting rods, each rod provided with a guide block slidable thereon, and means whereby the guide-blocks are secured to the upper and lower sashes of the window.

2. In a sash-holder the combination of a block having ends provided with oppositely projecting rods, an upper and lower guideblock having vertical holes to receive said rods, and means whereby the guide-blocks are secured to the upper and lower sashes of a window.

3. The combination with the up )er and lower sashes of a window, of a block seated upon the meeting-rail of the lower sash, said i In testimony whereof I aHiX my signature in presence of two-witnesses.
